MANUFACTURE OF CUTLERY-HANDLES.

SPECIFICATION forming part of Letters Patent No. 410,834, datedSeptember 10, 1889.

Application filed March 13, 1889. Serial No. 303,109. (No model.)

To aZZ whom it may concern.-

Be it known that I, HUBERT C. HART, residing at Unionville, in thecounty of Hartford and State of Connecticut, have invented certain newand useful Improvements in Handles for Cutlery; and I do. declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to an improvement in handles for cutlery, andparticularly for knives and forks, the object being to produce a strong,durable, and light article at small cost.

Vith these ends in view my invention consists in certain new methods forforming handles for cutlery from a blank of peculiar shap e, which willbe hereinafter described and claimed.

In the accompanying drawings, Figure lis a plan view of my improvedhandle-blank. Fig. 2 is a view in side elevation of a handle developedfrom such a blank. Fig. 4c is a View in transverse section, on the linea I), through the drawn end of the handle. Fig. 3 is a View in sideelevation of the handle after it has been welded and finished. Fig. 5 isa View in transverse sect-ion, on the line cc, through the welded partof the handle; and Fig. 6 is a view showing how the handle is assembledwith another part, aknife-blade being chosen for illustration.

As herein shown, the blank consists of a fiat piece of sheet metalhaving an enlarged 'central portion A and two narrow straightedgedleaves 13, having square ends and extending in opposite directions fromthe said central portion, the curved edges whereof merge into them. Thisblank is subjected to a drawing and forming operation, whereby itsenlarged central portion is drawn out into a hollow rounded seamless end0, and whereby its leaves are longitudinally folded to form the sides DD, which are brought together edge to edge and constitute a continuationof the drawn end of the handle. It will be understood that the blankwill be proportioned and shaped so that these results will occur when itis drawn and folded. After the handle has been developed its leaves arewelded or otherwise secured together, after which its whole exteriorsurface is finished. Preferably a rivet E is passed through the saidleaves and the bolster F of the part to which the handle is to beunited. After this the whole thing is hot-welded in dies.

A handle constructed as described cannot leak at its end, whereas theordinary hollow handle having a seamed end is very liable to leak, onaccount of the diiiiculty of perfectly uniting the parts on a curvedline. My improved handles also wear better than a handle having its endseamed, because the finish always wears off the seam sooner than elsewhere and exposes the seam. also easy to form and finish, and when doneis of fine appearance.

I would have it understood that I do no limit myself to the exactconstruction shown and described, but hold myself at liberty to makesuch changes and alterations as fairly fall within the spirit and scopeof my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A sheet-metal blank for cutlery-handles, consisting of an enlargedcentral portion having outwardly-curved side edges adapted to be drawninto a cup to form a seamless buttend for the handles, and twocorresponding leaves extending in opposite directions from the saidcentral portions, having straightedges and of uniform width throughoutand adapted to be folded to form the upper part of the handle,substantially as set forth.

2. A method of making cutlery-handles,

. consisting in part in drawing the central portion of a suitable blankinto a cup forming a seamless butt-end for the handle, and transverselyand longitudinally folding the two ends of the blank to conform them tothe exterior curvature of the cup and to bring them into line with thelength thereof.

3. A method of making cutlery-handles, consisting in drawing the centralportion of a blank into a cup and transversely and longitudinallyfolding the two ends of the blank and uniting the edges of the saidfolded ends.

4. A method of making cutlery-handles, consisting in drawing the centralportion of The handle is 10 a transverse rivet, hot-welding their edgestogether in dies, and finally finishing the handle.

In testimony whereof I have gned this specification in the presence oftwo subscribing Witnesses.
